The research field of the group are inverse problems with a strong focus on various applications from medical imaging and physics.  A special interest are dynamic inverse problems and online reconstruction from dynamic data. The core area in medical imaging consists of magnetic particle imaging (MPI). MPI allows the visualization of the concentration of magnetic nanoparticles inside the blood flow without use of any radiation. Another core area are inverse problems in physical applications such as ptychography and X-ray physics.
